To start off this new thread, I'd like to repost something I said in the last one. It's where Rocketshipping started and how far its come.
We start off with two crooks that are out to steal rare and valuable Pokemon. We later learn in the shipwreck arc that they care for each other as more than just partners, and the bond continues to show even more in Guardie and Kojiro. Musashi learns that Kojiro would never leave her for money, but that changes a bit later... We continue on with fearhugs and stuff throughout OI and Jouto... but at the end of it all, nothing has really changed.
Musashi begins doing Contest, cause a rift between her and Kojiro. Musashi sucks at them, cheats, and even abuses Kojiro's Pokemon. Kojiro seems to be becoming more disinterested in her. Near the end of the series we learn that Kojiro doesn't want to marry Musashi, but Musashi doesn't feel the same way... she still cheats and sucks at Contests, so once again, nothing really changed since the beginning of the series. The break up for a bit, but that just reaffirms their bond more than actual character development. Again, nothing really changes due to that episode.
Diamond and Pearl
We pick up where we left off last time. Musashi decides to stick with one persona and doesn't cheat at first. When that doesn't work, she has Kojiro and Nyasu rig a Contest. However, they never do, but Musashi wins anyway! Kojiro theorizes it's because the pressure was off Musashi so she could relax and just be herself.
Eventually Musashi find out she won the Contest on her own. She gets kinda a big head about it and bombs the next two. I guess she gets it through her head that she should practice and just be herself again, (I wish Tomioka had been more clear on this) and she ends up winning her second ribbon!
Pausing Contests for a bit, we have yet another break up episodes. This one, however, is it a bit different. It impacts Kojiro in that he seems to think only the hope of success as a team is keeping them together. He becomes extremely pro Rocket-Dan and starts taking charge more often. We once again revisit Musashi's fear that Kojiro would leave her for money. It's unclear whether she finally understands that he never would.
Back to Contests. Due to the success of them (and possibly Kojiro being in her shoes, it's hard to say right now.) Kojiro becomes much more supportive and no longer has any problem with Musashi doing them or even using his Pokemon! He also seems to think she actually has realistic chances to win now. However, he becomes confused whenever she puts this above Rocket-Dan work. Which brings to where we are now. On the cusp of Musashi winning her fifth and final ribbon, and entering the Grand Festival.
